What happens to the pressure if the gas volume is cut in half while n and I are held constant?

Answer: You can use Boyle's law, which states that pressure is inversely related to volume when other variables are held constant. If the final pressure of a gas is half of the initial, the volume must double if temperature is to remain the same.

What are base pairs

never [62]

Base pairs are more biology but they are what make up DNA there are 4 (adenine, thymine, guanine, and cytosine) they each pair with each other (A to T and G to C).

Question 1:

Alona [7]

Question 1:

(a) Sulfurous acid: H2SO3

Sulfuric acid: H2SO4

(b) Nitrous acid: H2NO2

Nitric acid: H2NO3

Question 2:

To calculate the pH, based on concentration of H+ ions, there is one formula:

$ph = - log_{10}(c(h + ))$

So the pH of this solution is

$- log_{10}( {10}^{ - 9} ) = 9$

(the solution is basic).

Answer:

- you have to do maths in all 3

- atoms make up everything even parts of a cel and theyre studied in chem and physics

- chemistry is used in biology by finding out what different substances are eg cytoplasm in a cell

At a given temperature, the elementary reaction A − ⇀ ↽ − B , in the forward direction, is first order in A with a rate constant

ZanzabumX [31]

Answer:

0.24

Explanation:

We are given that

Rate constant for A= $k=0.0180/s$

Rate constant for B,k'=0.0750/s

We have to find the value of equilibrium constant for the reaction

$A\rightleftharpoons B$

Equilibrium constant, for k= $\frac{k}{k'}$

Using the formula

$k=\frac{0.0180}{0.0750}=0.24$

Hence, the value of the equilibrium constant for the reaction

$A\rightleftharpoons B$ at this temperature=0.24

what bonding is similar to ionic bonding, except there are no high-electronegativity atosms present to accept any electrons that

kenny6666 [7]

Answer:

Metallic bonding

Explanation:

Ionic bonding involves the transfer of electrons from a highly electropositive metal to a highly electronegative nonmetal.

The metallic bond is somewhat similar to the ionic bond since there are also charged positive metal ions. The only difference is that there isn't any electronegative element that accepts the electrons.

In a metallic bond, the positively charged metal ions are bound together by a sea of mobile electrons. The attractive force between the metal ions and the mobile electrons hold the metallic crystal lattice together.
